89 Category 2: Civil Structures 2 Contact Ir. Rob van Gestel, Frank Havermans Address Leostraat 4 5615BM Eindhoven, The Netherlands Website www.archimedes-bouwadvies.nl Archimedes Bouwadvies BV is a structural engineering office located in Eindhoven, The Netherlands. Projects range from civil engineering to structural engineering for new and existing buildings for educational, industrial, residential, retail, leisure and office purposes. After having created the structural design of the school building, Archimedes also participated in the pedestrian bridge project team, being responsible for the structural design of the bridge. Owner PlatOO / Community of Son en Breugel Architect Frank Havermans General Contractor Frank Havermans Engineering Office Archimedes Bouwadvies BV Construction Period 04/2015 - 08/2015 The new primary school De Ruimte is a part of the Sonniuspark development, an expansion of the village of Son en Breugel. In order to create a safe connection for pedestrians between the Sonniuspark and the school, the village and the school launched a design contest. The challenge was to create a pedestrian bridge over an existing bicycle road. The contest was won by international award winning sculptural artist Frank Havermans. In their search for ways to make the 14 m span, the artist and the engineer joined forces, resulting in a sculptural web of corten steel strips landing on two different spots in the Sonniuspark. The only way to gain an idea of stress and deflection was to model this structure in SCIA Engineer. The bridge consists of corten steel strips with varying dimensions. The strips used have a thickness of between 12 and 20 mm. The height of the strips varies from 250 mm at the landing to 600 mm at the centre of the bridge. The bridge is shaped like a tripod, built up as a web of welded steel strips. The web is covered by oak flooring. SCIA Engineer proved its value by giving insight into the stress of the steel strips and the overall deflections of the bridge. At an early stage we started using SCIA Engineer more or less as a sculptural tool. The results of the calculations were used in the dialogues with the artist, after which we modified and optimized positions and dimensions of strips in the web. Eventually this resulted in a clear and logical structure, which stayed within budget. Pedestrian Bridge “De Ruimte” - Son en Breugel, The Netherlands SE Archimedes Bouwadvies BV
